  • CORE SAMPLING POLICY  Back to top
    1. All samples must be selected by the customer during their visit to the CRC. If a customer wishes to sample a core being viewed, they will consult with the CRC staff member working at the front desk. The CRC staff member will determine if there is sufficient material to sample.
    2. 1.1. Sampling of archived core, both plugged and slabbed sections is permitted if more than 1/3 of the cross-section remains.

      1.2. If not enough archive slab remains for sampling, CRC staff will determine if the butt section is available for the well requested.

    3. The CRC contains a wealth of analog and digital data on cores from previous sampling and analysis sessions. Prior to taking new splits, it is highly recommended that the customer look through the well analyses files to see if data and/or thin sections already exist for the sample(s) requested. The CRC is in the process of making all data available via the CRC Website. Please check to see if data on the samples requested are already available on the CRC Web site.

    4. Core sampling:
    5. 3.1. Individual core samples taken may not exceed one-cubic inch or a one-inch plug. If a larger sample size is needed, a scientific justification must be submitted. CRC staff will determine if approval can be granted for larger sample(s) on a case-by-case basis.

      3.2. No more than one sample per six inches of core may be taken, i.e. side-by-side plugs/sampling is not allowed. Plugs will only be taken perpendicular to the axis of the core. Samples will be taken so that a continuous vertical portion of the core remains. Sampling that would result in the total loss of a core interval is not permitted.

      3.3. All samples will be cut by the CRC staff.

      3.4. The CRC expects to receive results (data, thin section, etc.) for each sample taken. Samples should not be collected in excess of the number that can be analyzed within the allotted six month time period.

    6. Temporary core removal:
    7. 4.1. Temporary removal of core from the CRC will be determined on a case-by-case basis, i.e. the need to run non-destructive tests that require specialized equipment not available at the CRC. A time frame for returning the core will be determined on a case-by-case basis. Outside labs must be able to start the analysis immediately upon receipt of core.

      4.2. Core may be removed from the CRC for slabbing. Core slabbing must be arranged and paid for by customer, and must have CRC approval. A time frame for returning the core will be determined on a case-by-case basis. Slabbed cores must be marked with depth intervals and directional arrows. Cores must be matched by the drilling marks, and the slab ends must fit together.

      4.3. Slabbed core must be returned with the thin slab in CRC archive boxes. The CRC will provide boxes to the slabbing company. All boxes must be labeled with the well name, township-range and section, operator, county, state, and depths. Butts are to be returned in the original boxes.

      4.4. Sampling is prohibited while cores are removed from the CRC.

    8. Any unused portion(s) of sample material, along with appropriate labeling, must be returned to the CRC within six months of sampling unless prior arrangements have been made with the CRC staff.

    9. Prior to removing samples from the CRC, a completed sampling form must be signed by a CRC staff member and the individual taking the samples. The name of the individual’s supervisor, company/organization name, business address, e-mail address, telephone number, and date must be legibly written on the form. Students must provide name and contact information for primary professor. Sampling forms are available at the CRC front desk.

    10. Generated data/acknowledgement:
    11. 7.1. Copies of any analytical results (i.e. chemical, paleontological, petrophysical, and petrographic reports, etc.) and/or any thin sections made from sampled core must be submitted to the U.S. Geological Survey’s CRC within six months of sampling. The data will be made publically available via the CRC website. Customers will not be allowed to view or sample additional material(s) until overdue results or thin sections are returned. Analytical data must be in specified digital format for analysis described in the Data Return Policy. Thin sections must be clearly labeled with the CRC library number, operator, well name, and depth.

      7.2. The data will be made publicly available at the CRC and via the CRC website and will become part of the public domain, even if the processing and/or analyses were paid for with private funds. Any interpretations based on the data need not be submitted.

      7.3. We request that the USGS Core Research Center be acknowledged as the source of the sample material and/or provider of related analytical data in any publication that contains results from studies of the CRC collections. We encourage including detailed information such as library number, API number, well name, location and sample depths which will enable future researchers to locate materials for additional investigations.


  • CUTTINGS SAMPLING POLICY  Back to top
    1. All samples must be identified by the customer while at the CRC. If a customer wishes to sample from the cuttings they are viewing, they will consult with the CRC staff member at the front desk. The CRC staff member will determine if there is sufficient sample available.
    2. 1.1. Sampling is allowed if the cuttings envelope contains more than 15 milliliters (ml) of material.

      1.2. If there is insufficient material in an envelope to sample, CRC staff will determine if there is a duplicate cuttings set available.

    3. The CRC contains a wealth of analog and digital data on cuttings/wells previously sampled. Prior to taking new splits, it is highly recommended that the customer look through the well analyses files to see if data and/or thin sections already exist for the sample(s) requested. The CRC is in the process of making its data available on the CRC Website. Please check to see if data on the samples requested are already available.

    4. Cuttings sampling:
    5. 3.1. If an envelope contains more than 15 ml of material, up to 5 ml of the remaining material may be sampled.

      3.2. No high-grading (picking out specific grains) of samples; all samples taken must be representative of the cuttings depth interval. If customer is observed high-grading samples, they may lose the privilege of sampling additional cuttings.

      3.3. CRC staff has the right to verify the amount of sample collected. If it is found that sampling protocols are not being followed, the customer will be required to correct the sample size of those samples out of compliance, and may lose additional sampling privileges.

      3.4. The CRC expects to receive results (data, thin section, etc.) for each sample taken. Samples should not be collected in excess of the number that can be analyzed within the allotted six month time period.

    6. Any unused portion(s) of collected sample material (along with appropriate labeling), must be returned to the CRC within six months of sampling unless prior arrangements have been made with the CRC staff.

    7. Prior to removing samples from the CRC, a completed sampling form must be signed by the individual taking the samples and a CRC staff member. The name of the individual’s supervisor, company/organization name, business address, e-mail address, telephone number, and date must be legibly written on the form. Students must provide name and contact information for primary professor/advisor. Sampling forms are available at the CRC front desk.

    8. Generated data/acknowledgement:
    9. 6.1. Copies of any analytical results (i.e. chemical, paleontological, petrophysical, and petrographic reports, etc.) and/or any thin sections made from sampled cuttings must be submitted to the U.S. Geological Survey’s CRC within six months of sampling. The data will be made publically available via the CRC website. Customers will not be allowed to view or sample additional material(s) until overdue results or thin sections are returned. Analytical data must be in specified digital format for analysis described in the Data Return Policy. Thin sections must be clearly labeled with the CRC library number, operator, well name, and depth.

      6.2. The data will be made publicly available at the CRC and via the CRC website and will become part of the public domain, even if the processing and/or analyses were paid for with private funds. Any interpretations based on the data need not be submitted.

      6.3. We request that the USGS Core Research Center be acknowledged as the source of the sample material and/or provider of related analytical data in any publication that contains results from studies of the CRC collections. We encourage including detailed information such as library number, API number, well name, location and sample depths which will enable future researchers to locate materials for additional investigations.


  • DATA RETURN POLICY  Back to top
    1. All thin sections, analytical data, and/or other products derived from sampling of the CRC collection must be submitted within six months from the date of sampling. If analysis is not performed, the samples must be returned. In addition, the CRC staff reserves the right to limit or restrict future sampling until data are submitted.

The CRC reserves the right to restrict additional viewing or sampling by affiliates of the company or school until all outstanding unused material, thin sections, or data have been returned/submitted.

  • THIN SECTION LOAN POLICY  Back to top
    1. Approval from a Core Research Center (CRC) staff member is required to borrow thin sections.
    2. Prior to removing thin sections from the CRC, a completed thin section loan form must be signed by a CRC staff member and the individual borrowing the thin sections. The name of the individual’s supervisor, company/organization name, business address, email address, telephone number, and date must be legibly written on the form. Students must provide the name and contact information of their primary professor. The thin section loan sheet must also list each individual depth for each thin section borrowed.
    3. Borrowed thin sections must be transferred from the thin section holders to the boxes provided by the CRC staff. Empty holders must be left in position in the drawer; they must not be removed.
    4. Thin sections must be returned within 30 days of the date borrowed.
    5. If borrower needs additional time after the 30 days, the loan may be renewed for an additional 30 days with permission of the CRC staff. If other requests for the thin sections are made during the renewal extension period, the borrower will be required to return the thin sections immediately.
    6. Borrowers are responsible for repair or replacement of any thin sections broken while on loan or during shipment. If a borrower wishes to check out a thin section with previous damage, the defects should be recorded on the thin section loan form and initialed by a CRC staff member.
    7. No more than 100 thin sections will be loaned to one individual/group at a time.
    8. The CRC does not ship thin sections. Thin sections must be picked up at the CRC. They may be returned in person or by mail. Borrower is responsible for return shipping costs and for securely packing the thin sections to prevent damage in transit.
